"Since it's our drinking water, everybody should have some interest in the lake and the quality of the water."

Spier will be leading an electro-shock fishing demonstrations at 11 a.m. and 1 p.m.

"We put an electric current into the water and it temporarily stuns the fish and they float to the surface where we can pick them," Spiers said. "And then after just a few minutes in the boat they recover and then we can put them back in the lake and they swim off and they’re fine. It’s really cool, it’s very fun."

The free event also includes narrated pontoon rides every hour starting at 10:30 a.m.
